TEST DETAILS
Interpretation guide:
AU/mL value Results Interpretation
<20 Negative No detectable antibodies to rubella IgM were found.
20.0-24.9 Equivocal Equivocal samples should be retested. Samples which are positive at the second test should be considered positive. Samples which are negative at the second test should be considered negative. If the result remains equivocal after repeat testing, a second sample should be collected no less than 1-2 weeks later.

Test includes:
Antibody detection and immune status ratio (ISR) to Rubella IgM.
Methodology:
Chemiluminescence
Synonyms:
RUBELLA IGM ANTIBODY, RUBELLA ANTIBODY
Clinical significance:
Rubella (German measles) is a usually benign childhood viral infection for which a vaccine is available. IgM antibody is detectable 11-25 days after the onset of exanthem, 12-25 days after vaccination, and in most infants with congenital rubella between 2 weeks and 3 months after birth. A positive rubella IgM antibody in conjunction with clinical findings may indicate an active or recent infection with rubella virus.
